Overdue invoice reminders
Mallow automatically marks past-due invoices as "overdue" in your portal and sends reminder emails on a fixed schedule. This process runs in the background so you don't need to manually follow up on unpaid invoices.
When an invoice becomes overdue
An invoice is marked overdue when its due date has passed. Mallow checks for qualifying invoices and updates each status automatically.
Reminder schedule
Overdue reminder emails are sent the day after the due date and repeat every 7 days while the invoice remains unpaid. The system uses an internal log to avoid sending duplicate reminders, so each invoice only receives one reminder per cycle.
Sending additional reminders
For sent or overdue invoices, you can manually resend a payment reminder from the invoice row menu.
Open the three-dot menu next to the invoice.
Select Resend invoice.
Confirm with Send Reminder. This emails your client to review and pay the invoice.
To remind a client about an unsigned agreement instead, see Send an agreement.
Who receives the reminders
Each reminder is sent to two groups:
Your client — the email address on the invoice
Your internal team — the team email associated with the account
How this fits with other automated emails
Subscription and recurring invoices already send renewal notifications, receipts, and billing reminders automatically. Overdue reminders are a separate follow-up flow that applies only to invoices that have not been paid by the due date.
